The consequences of parental exposure to epidermal growth factor (EGF), for progeny cell cycle times was investigated. Slowly dividing mouse 3T3 fibroblasts were exposed to EGF for 8 hr, the EGF was withdrawn, and the cell cycle times of parental and progeny cells were measured by time‐lapse video microscopy. It was observed that exposure to EGF induced a round of cell division following a lag phase of approximately 8 hr. The progeny of these cells exhibited accelerated cell cycle times compared to cells that had not been exposed to EGF. Parental cell division time was significantly correlated with progeny cell cycle time. Sibling progeny cell cycle times were also significantly correlated. EGF can therefore apparently exert an effect on the cell cycle times of more than one generation of cells.
